Abstract

A data input system includes a wireless keyboard and docking station, which can be connected to a computer system. When the keyboard and docking station are mechanically connected, the docking station is configured automatically to generate a new pairing code or key that is different to a previously-generated one. This new code/key is then transmitted back to the keyboard over a wireless control link and the keyboard and docking station then set up a paired data channel over which data from the keyboard is transmitted wirelessly to the docking station, and so the computer system. When a new mechanical connection is made, e.g. using the same or a different keyboard, the process repeats so that a new pairing code or key is generated, thus avoiding interference with other keyboard(s) that were previously paired with the same docking station.

Claims

1. A system comprising:

a data input device; and

a docking station for association with a computer system,

the data input device and docking station being configured in response to being in proximity to one another to establish a paired data communications channel for transmitting data wirelessly from the data input device to the docking station, the paired data communications channel being established using a pairing key or code that is generated automatically when the data input device is in proximity of the docking station and which is different from a previously-generated pairing key or code.

2. A system according to claim 1, wherein the docking station is configured to generate automatically the pairing code or key and transmit it back to the data input device.

3. A system according to claim 2, wherein the docking station comprises a wireless transmitter/receiver configured to transmit the pairing code or key back to a wireless transmitter/receiver of the data input device using a wireless control channel automatically set up using predefined parameters in response to the input device and docking station being in proximity.

4. A system according to claim 3, wherein the or each of the wireless transmitter/receivers are configured automatically to reduce its/their transmit power in response to the input device and docking station being in proximity.

5. A system according to claim 1, wherein the system is configured such that the pairing code or key is generated in response to the data input device and docking station being mechanically connected from a previously non-connected state.

6. A system according to claim 5, wherein the system is configured such that the pairing code or key is generated in response to the data input device and docking station being mechanically connected by respective electrical terminals.

7. A system according to claim 6, wherein the system is configured such that the pairing code or key is generated in response to the data input device exchanging electrical signal(s) with the docking station through the electrical terminals.

8. A system according to claim 5, wherein the docking station is configured to provide a charging current to the keyboard when mechanically connected.

9. (canceled)

10. (canceled)

11. A method comprising:

detecting a data input device and docking station being in proximity to one another;

in response to said detection, automatically generating a pairing code or key at one of the input device or docking station and transmitting it to the other, the key or code being different from a previously-generated key or code; and

establishing a paired, wireless data connection between the input device and docking station using the pairing code or key for the subsequent transfer of data_from the data input device to a computer system associated with the docking station.

13. (canceled)

14. A system comprising:

a data input device;

a docking station; and

a receiver device for association with a computer system,

the data input device and docking station being configured in response to being in proximity to one another automatically to cause wireless transmission of a control signal to the receiver device, and

the receiver device being configured in response to receipt of the control signal to establish a paired data communications channel with the data input device for the subsequent receipt of data wirelessly therefrom, the paired data communications channel being established using a pairing key or code that is generated automatically by the receiver device upon receipt of the control signal and which is different from a previously-generated pairing code or key.

15. A system according to claim 14, wherein the receiver device is further configured to established a paired data communications channel with the docking station for receipt of a subsequent control signal.

16. A system according to claim 14, wherein the data input device and docking station are configured automatically to cause wireless transmission of the control signal in response to being mechanically connected to one another.

17. A system according to claim 14, wherein the docking station is configured to provide a charging current to the keyboard when mechanically connected.

18. A method comprising:

detecting a data input device and docking station being in proximity to one another;

in response to said detection, automatically transmitting a control signal wirelessly from the docking station to a remote receiver device associated with a computer system;

at the remote receiver device, generating automatically a pairing code or key that is different from a previously-generated pairing code or key and transmitting it wirelessly to the data input device; and

establishing a paired, wireless data connection between the data input device and the remote receiver device, using the pairing code or key, for the subsequent transfer of data from the data input device to the computer system associated with the remote receiver device.
